To all whom itmag concern: 7

Be it known that we, FRANK J. Mormon and JOHN L. Mormon, citizens of theUnited States, and residents of Newark, in the county of Essex and Stateof New Jersey,

have invented a new and Improved Gearing Driving Unit, of which thefollowing is a full, clear, and exact description.

This invention relates to gear driving units, and has particularreference to a gear driving unit for chemical agitators, such as paint,pulp and sugar mixers.

An object of the invention is to provide a unit in which certain of theparts may be readily removed for repair and replacement withoutdismantling the entire apparatus.

Another object resides .in the provision of means whereby stresses towhich the various parts are subject are more uniformly distributed,resulting in a stronger unit.

A further object resides in the provisionof means whereby the drivingand driven shafts are so arranged that a plurality of units may bereadily connected together and driven from a common source of power.

Astill further object resides in the particular construction andarrangement of parts hereinafter described and claimed and shown in theaccompanying drawings.

The invention is illustrated in the drawings, of which v p Figure 1 isan elevation of the unit;

Fig. 2 is a plan view of the unit; and

Fig. 3 is a view showing a pluralityof units connected together,

As shown in the drawings, the unitis embodied in the form which isparticularly applicable for attachment to a support 1, which, in thepreferred application, is the top cover or platform of a chemicalagitator which is in the form of a tank. To this platform is. suitablybolted or otherwise connected a casting having a U-shaped portion A anda rectangular portion B. These portions have a common leg 2. The legs 2,3'

and 1 of the casting which extend vertically are provided with suitablebearing portions 5, 6 and 7 which are properly alined to receive a shaft8, which is the driving shaft. The driving shaft is provided with theusual pair of pulleys 9 and 10, one of which is idle, adapted tocooperate with a belt 11 to drive the shaft 8. Any suitablebelt-shifting mechanism, such as 12, maybe provided. These pulleys 9 and10 are disposed within the U-shaped portion A of the casting.

Patented Dec. 2?,1921.

Within the rectangular shaft'portion B of 7 the casting is abevel gear13 mounted on the shaft 8 and adapted to mesh with a-bevel gear 14 fixedto a shaft 15 which extends vertically substantially midway of thecasting portion 13 and is journaled in bearings 16 and 17 in the lowerand upper portions of this casting, respectively. This shaft 15 ex tendsdownwardly through the support or platform 1 into the'agitator or otherreceptacle and to it is connected any suitable agi- .tating means. Itis, of course, apparent that this shaft may be connected to any othersuitable device to be driven, regardless of whether it-is contained in areceptacle or ranged that the shaft .8 and the'shaft 15 are laterallydisposed With respect to each other,

so that the shaft 8 can be extended from one side of the portion B tothe other and be suitably journaled at each end. ticular disposition iseffected by cutting the teeth of the bevel gears in such a manner as topermit of this offset of the driven shaft with respect to the drivingshaft. Further,

' it will be noted that the bearings 6 and "(are provided with removableplates which are This pardisposed on the side of the bearing portions wopposite the shaft 15. On the other hand, it i will be noticed. that thebearing portions 16 and 17 are provided with removable plates disposedon the side ofthe respective bearrangement' of the removable plates ofthe various bearingportlons is convenient In that the shafts 8 and 1 5and their cooperating parts may each be removed without disturbing theother. This is'particularly ading portions opposite the shaft 8. Thisarin the form of a removable plate, so that the entire shaft 8,including the pulleys 9 and 10, can be removed as a unit. 7

By supporting the shaft 8 at opposite ends,

in the casting portion B the strain which is ordinarily upon the drivingshaft 8 when I nation of stresses and strain also enhances V hanr es therigidity, simplicity and eflioieney extended to the end of the bevelgear l3 and yiism'a i n a ing rba i s, smal as 6, is substantiallyeliminated. This elimn the funrtioning and reduction of friction in shever ie abaa i-ns p and 11 5 th shaft 15, so thatin this case thetransm1s-' sion of power from one shaft to the other is efie ted with aminimum loss due to friction. This alsorresults in an-inorease-in thelife ofthe parts far beyond that hitherto obtainable. i

ous gearing shafts and pulleys in the iform ofan integral unitarycasting also onof the "transmission of power by means of i this device.

As shown in Fig, 3,by offsetting shaft 8 with respect tolshaft 15 it ispossibleto exf tend theshaft 8evenbeyond its own ordi unit and connectby a flexible coupling 21 0f any suitable type toaeorresponding-shaft 22of another'unit such as represented' bytheletter C in Fig. 8. Inthisfigure, the bevel gear 13 is-mounted loosely around the shaft 8- andisadapted to mesh with theolutchmernber 13 which is rigidly connected tothe shaft 8. Thiselutohmemher is operated by a clutch lever 14- to engage the bevel gear l with the movement of the shaft 8 at will; Thispermits one or more driving units to be operated ata time regardless ofthe number of units of the series 'which may be operating. In thismanner anynumber of units may be assembled and operated by a singlesource of power throughthe pulleysfi and 10l Hitherto in the operationof devices of this character it has notbeen possible to drive more thanoneunit at a time fromtthe same source of power without the use ofcomplicated connecting means.

It is, therefore, applargentithat I have provided a simple, compact andefficient unit which can be used byitself or n connection nism, with aminimum lossduekto friction out departing from the spirit, of the in-;vention. a
